BOARDING SHOT.

SPECIFICATION forming part of Letters Patent No. 703,320, dated June 24, 1902.

Application filed January 30,1902. Serial No. 91,931. No model.)

To all whom, it may concern:

Be it known that 1, CHARLES TATHAM, a citizen of the United States, residing at Manhattan borough, New York city, in the county and State of New York, have invented new and useful Improvementsin Boarding Shot,of which the following is a specification.

By means of this invention good or marketable shot can be rapidly or satisfactorily separated from the shot which is defective or flattened or considered unsatisfactory.

The invention resides in certain novel features of construction set forth in the followin g specification and claims and illustrated in the annexed drawings, in which- Figure 1 is a side elevation of a boarding device embodying the invention. Fig. 2 is a plan view of Fig. 1. Fig. 3 is a section along a: 00, Fig. 1.

In the drawings is shown a support com prising legs a and a top or frame I). A board is shown at c of suitable smooth material. Marble or polished steel plate or like mate-' rial can be used. This table is suitably inclined so that a spherical bodysay a perfect shot or globuleof lead-placed on the table will start or roll itself off or to the lower end or edge of the table. Animperfect shot coming to rest with a fiat or defective portion thereof on the table will remain stationary thereonthat is, such imperfect shot will not start of its accord to run or roll down or along the table, but has to be scraped or moved off or given a push or impetus before it will start rolling down. As presently explained, this table is combined with what may be called a stop for temporarily arresting shot passing over the table and a scraper for clearing the table. The stop is formed of any suitable arrangement, a brush or longbristled broom or broom-head f having been found satisfactory. Say a charge of good and bad shot mixed which has come from the high part of the table rests against the stop and the latter makes a step forward or toward the lower end of the table. The good shot will roll or follow this stop until it comes to a temporary rest and then again follow the stop as the latter moves a step forward, to again temporarily rest and again move for- The good shot thus keeps up to the ward.

stop as the latter passes step by step along a the table until the stop clears the lower edge of the table, when the good shot rolls off the table.

The intermittent stoppages of the bunch of shot cause the bad or defective shot to be arrested or remain stationary on or along the table, while the good shot, as stated, separates itself out or rolls off such table. After the good shot has rolled or passedofi the defectiveshot is removed by what may conveniently be called a scraper, (shown at g.) The scraper may also be a brush or broom or any suitable sweeping or brushing device. A board with a flexible rubber strip at the lower edge has been found practicalfor scraping the defective shot down and off the table.

The good shot rolling off the table is directed by a flap m into a box or receptacle n. Suitably turning or shifting the flap after the good shot has been cleared off the table and before the bad shot is started will cause the latter when being swept or cleared 06 the table to strike the flap to be guided or directed into receiver 0. The flap being then shifted back will direct the next charge of good shot to be again directed into box n, and

so on. t

The actuation ofthe stop and scraper and of the flapis mechanical.

In the drawings is shown a suitable carrier for the stop and scraper comprising chains e, carried about by sprocket-wheels d, driven by any suitable appliance. The stop-brush f in passing over the table comes into contact with the racks or serrations p at the sides of frame I) and is thereby given a wavy or up-and-down motion, or rather the intermittent or step-bystep motion along the table, which causes the defective shot to stop traveling or be left behind the good shot. While the stop f contacts with or is arrested intermittently or at the shoulders 19, the scraper g travels continuously or is so narrow or cutaway as to clear or pass freely betweenthe serrations p without touching the latter. A second stop and scraper are shown at f g; but they are not necessary for explaining the invention; but of course the capacity of the machine can be increased by a greater number of such parts.

The device operates as follows: Say the valve 11 of the shot chute or reservoir has been momentarily opened for a certain quantity of shot to roll and be momentarily arrested against stopf, Fig. 1. Then the good shot will follow the gradually-advancing stop and the defective shot will remain on the board. After the good shot has rolled off the board the scraper g follows along to clear off the poor shot. The flapm has an arm q, and after a scrapersay g'-has cleared off the defect ive shot in front of it and swings up or about front sprocket-wheel 01 such scraper strikes arm (1 and tilts the flap about its pivot 2 to incline to or into receptacle 01. As the oncoming stop-brushfclears the end of the board or swings up about front Wheel d an end or part of this stop fstrikes the free end of lever 8, having at its other end'link t, connected to the flap m, so as to swing the lever and return the flap to the position inclining to the receptacle 0. The valve 1' is normally held closed by spring 3. This valve connects with or is secured to a lever 4, having fixed pivot at 5 and linked at 6 to lever 7, having pivot fixed at 8. To this lever 8 connects lever 9, the inner end of which is in the path of lugs 0. As these lugs move about with one of the chains 6 the levers 9 and 7, with parts 6 and 4, are moved or oscillated to momentarily open valve i, but as a stop clears lever 9 the valve t' again closes, so that a limited amount of shot at a time is discharged onto board 0.

While the scraper g in this case is shown moving continuously, still it might be made to move step by step, the same as the stop, if desired.

What I claim as new, and desire to secure by Letters Patent, is-

1. In a machine for boarding shot, the combination with a table for the passage of the shot, of a movable stop for arresting the passage of the shot upon the table, and a scraper traveling in the path of the stop for removing the shot from the table.

2. In a machine for boarding shot, the combination with a table for the passage of the shot, of an intermittently-travelin g stop moving over the table and adapted to suitably arrest the passage of the shot, and a continuously-moving scraper traveling in the path of the stop for removing the shot from the table.

3. A table and a rack or shoulders combined with a stop made to contact with the shoulders, and a scraper made to move continuously clear of the shoulders.

4. A device for boarding shot comprising a table, a continuouslymoving carrier or chains, a stop and. a scraper actuated by the carrier and shoulders for imparting to the stop a step-by-step motion.

5. A machine for boarding shot comprising a table, a stop and a scraper made to pass over the table, and a flap alternately operated by said stop and scraper for discharging the shot from the table in opposite directions.

6. In a machine for boarding shot, a table for the passage of the shot, a carrier, a stop and scraper carried thereby, a valve for feeding the shot to the table, an actuating-lever for the valve, and lugs actuated by the carrier and engaging the valve-actuated lever for suitably operating it.

7. In a device for boarding shot, a table for the passage of the shot, a carrier, a stop secured to the carrier and traveling in a stepby-step manner, a scraper connected to the carrier and operating in the passage of the stop in a continuous manner, and an intermittently-actuated shot-feeding valve for suitably supplying the shot to the table.

8. In a machine for boarding shot, a table for the passage of the material, an intermittently-traveling stop operating upon the table, a continuously-moving scraper operating upon the table, and a shot-directing flap shifted by the stop and the scraper for suitably directing the discharge of the shot as it passes from the table.

9. In a machine for boarding shot, a table for the passage of the shot, a traveling stop moving over the table, a traveling scraper moving in the path of the stop, a shot-directing fiap arranged in suitable relation to said table, and an arm and shifting-lever connected with the flap and engaged and operated by the stop and scraper for suitably shifting the flap for directing the passage of the shot when discharged from the table.

10. In a machine for boarding shot, the combination with a table for the passage of the shot, of an intermittently operating means for feeding the shot to the table, an intermittently-operating stop traveling over the table for interrupting the passage of the shot, a continuously-moving scraper operating over the table for removing the shot therefrom, and means operated by said shot and flap for directing the discharge of the shot from the table.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

CHARLES TATHAM.
